The document describes standard CT image reconstruction (FBP and iterative reconstruction) and various image processing and analysis tools, but does not mention AI or ML.
No
The device is a diagnostic imaging system (CT scanner) used to create images of the body, not to treat conditions.
Yes
Explanation: The "Intended Use / Indications for Use" states that the device can be used as a "whole body computed tomography X-ray system," and the "Summary of Performance Studies" section mentions that the "Results indicated that the images were of diagnostic quality." This indicates the device is used to diagnose medical conditions.
No
The device description explicitly states that the system is composed of hardware components such as a gantry, patient couch, and operator console, in addition to software. It also mentions image acquisition hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is a "whole body computed tomography X-ray system." It describes the process of acquiring X-ray transmission data and reconstructing it into cross-sectional images of the body. This is a diagnostic imaging device, not a device used to examine specimens derived from the human body.
- Device Description: The description details the physical components (gantry, couch, console) and software features related to image acquisition, reconstruction, and visualization. These are all functions of a medical imaging system.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, reagents, or any other elements typically associated with in vitro diagnostics.
Therefore, the NeuViz Prime Multi-Slice CT Scanner System is a medical imaging device, specifically a CT scanner, and not an IVD.
